We caught wind of an upcoming video offering from Barnes & Noble a couple of weeks back, as part of a tip on new tablet offerings from the company. And while we've yet to hear anything official on the latter, this morning the bookstore pulled back the curtain on Nook Video, a new service boasting support from heavy hitters like HBO, Sony, Warner Brothers, Viacom and Disney. The fruits of those partnerships include standard and high-def movies and TV shows like The Avengers, Brave, The Amazing Spider-man, Breaking Bad, The Daily Show and Game of Thrones, which can be watched on Nooks, and non-Barnes & Noble tablets and smartphones, courtesy of a forthcoming free app from the retailer, letting you pick up where you left off on different devices.
